I slightly prefer Columbia's undergrad program, but it might be harder to get a high GPA at Columbia due to grade deflation. With Brown, I am guaranteed a spot at Alpert Medical School, no MCAT, only requirement is to get a 3.0 or higher in two biology classes, and to take 2 semesters of inorganic chemistry, physics, and 1 semester or organic chemistry (these ones can be taken credit no credit). No scholarship for either.
Is it unwise to think about shooting higher for med schools and forgo a (virtually) guaranteed admission?
